Quantum gravity around ultracold black holes from DSSYK
Francesca Mariani, Thomas G. Mertens, Jacopo Papalini +1
We propose a quantum description of the ultracold Reissner-Nordström de Sitter black hole via a specific flat space limit of the double-scaled SYK model. Fluctuations in this regim…
Quantum JT Gravity in a box as a Pöschl-Teller Scattering Problem
Luca Griguolo, Jacopo Papalini, Lorenzo Russo +2
We present a canonical quantization of Jackiw-Teitelboim gravity with finite Dirichlet boundary conditions, using the geodesic length between the two boundaries and its conjugate m…
A new perspective on dilaton gravity at finite cutoff
Luca Griguolo, Jacopo Papalini, Lorenzo Russo +1
The formulation of two-dimensional quantum gravity at finite cutoff remains an open problem. We revisit this question in JT gravity from two perspectives: the closed-channel bulk p…
Wormholes, branes and finite matrices in sine dilaton gravity
Andreas Blommaert, Adam Levine, Thomas G. Mertens +2
We compute the double trumpet in sine dilaton gravity via WdW quantization. The wormhole size is discretized. The wormhole amplitude matches the spectral correlation of a finite-cu…
De Sitter holographic complexity from Krylov complexity in DSSYK
Michal P. Heller, Fabio Ori, Jacopo Papalini +2
We utilize the recent connection between the high energy limit of the double-scaled SYK model and two-dimensional de Sitter solutions of sine dilaton gravity to identify the length…
Krylov spread complexity as holographic complexity beyond JT gravity
Michal P. Heller, Jacopo Papalini, Tim Schuhmann
One of the important open problems in quantum black hole physics is a dual interpretation of holographic complexity proposals. To date the only quantitative match is the equality b…
